I have newly pruchased AT&T DSLl fast internet service. initially ,I was getting AT&T page when I click into the internet. Now I get Yahoo and I don't want my internet page as Yahoo. How do I get it back?

Are you referring to your home page -- the first page you see when you sign on? Here's a way to fix this: In your browser (Internet Explorer, Firefox, Safari, etc.) there is a Preference or Internet Options choice in your menu bar. By choosing that you'll open up a dialog box; look for "Home Page" or something similar. You can simply paste in your favorite Web site address and save that choice, and your Web browser will always start by displaying your favorite Web site. Does that help, or have I misinterpreted your question?
